What about a soft launch?
You know, a store will hold a soft opening, where it opens unannounced, so they can get the kinks out with a smaller crowd. Then they hold the big grand opening.
Remember that rumor we heard about a May 17 launch and a June 29 one?
What if Sprint starts selling the Pre on May 17 or 24 unannounced, telesales only, to see how it goes on a smaller scale, then it cranks up the hype machine and sells it with the big launch at stores in June?
